YAY! It's my birthday! The day I made this beauty!
It is VERY possible the melody already excists, but don't be hard on me because of that. I know it can excist. At school, we had to do the Shuttle Run Test (hence the name). You hear music and then, when you hear a beep, you need to run to the other side of the room, going faster and faster. And THIS is the melody you hear. Call it a mix if you want.
